Apparently I do not have it wrong- heres the quote from Tommy Chong himself-but im sure youve already heard this because you guys are good friends.
"It's hard to pinpoint what's working as I am on medication to shrink the prostate, which shrinks the cancer. The problem with the hemp oil is getting it to the affected area. My numbers have gone down tremendously and I credit that in part to the oil. My own observation is that pot gives you cottonmouth, which makes you drink more water. Water has enormous healing powers"
Heres the whole article from celebstoner- you can also find the Tommy Chong interview in High Times where he continues saying that he is not 100% cancer free.
And on twitter he says the hemp oil is working to treat the cancer, bc he can not say its cured the cancer- why? because he also says he is not completely cancer free
